Abstract
A paint spray booth and air supply arrangement includes a main fan for blowing air and an air supply plenum in fluid communication with the main fan for receiving blown air therefrom. A support grid is positioned beneath the air supply plenum and includes a plurality of grid openings. A painting chamber is positioned beneath the support grid. A plurality of diffuser modules are positioned within the plurality of grid openings, respectively, for directing blown air from the air supply plenum in a substantially vertically downward direction through the painting chamber. Each diffuser includes an adjustment feature for selectively adjusting the speed of air directed therethrough. An apparatus is provided for individually adjusting the adjustment feature in each of the plurality of diffuser modules for creating areas of variable air speed through the painting chamber corresponding with each diffuser module while the diffuser modules being adjusted are supported on the support grid. Accordingly, the need is eliminated for removing the diffuser modules for individual adjustment.
